Thank you all for your responses!
I thought about this a lot and I think the reason I'm not able to let go of the negative things, is because I don't want to. I need them to keep my wall up... because I know if I take my wall down, I will be hurt even more in the coming days, when he turns back into Mr. Hyde.
p.s. of course we didn't talk today - no surprise. AND he decided to go out again tonight after work without telling me or answering my phone calls at 1:30 am (I guess he thinks he is punishing me because I didn't answer his text when he asked if I would come pick him up tonight - I fell asleep and didn't hear my phone)
